Dynamical heterogeneity and jamming in glass-forming liquids
Naida Lacevic, Sharon C. Glotzer
The relationship between spatially heterogeneous dynamics (SHD) and jamming is studied in a glass-forming binary Lennard-Jones system via molecular dynamics simulations. It has bee…
Spatially heterogeneous dynamics and dynamic facilitation in a model of viscous silica
Michael Vogel, Sharon C. Glotzer
Performing molecular dynamics simulations, we find that the structural relaxation dynamics of viscous silica, the prototype of a strong glass former, are spatially heterogeneous an…
String-like Clusters and Cooperative Motion in a Model Glass-Forming Liquid
Claudio Donati, Jack F. Douglas, Walter Kob +3
A large-scale molecular dynamics simulation is performed on a glass-forming Lennard-Jones mixture to determine the nature of dynamical heterogeneities which arise in this model fra…
Dynamical heterogeneities in a supercooled Lennard-Jones liquid
Walter Kob, Claudio Donati, Steven J. Plimpton +2
We present the results of a large scale molecular dynamics computer simulation study in which we investigate whether a supercooled Lennard-Jones liquid exhibits dynamical heterogen…
